Microsoft is hosting BBC’s recording (7 ~1 hour segments) of Feynman’s lectures* at Cornell from 1964. At the bottom of each segment is a scrolling transcript. At the top you can turn on a couple scrolling text commentaries. Along the time-line of each lecture are ‘eggs’ marking what’s being dictated.
Anyways, I know there are some Feynman fans here and a search didn’t turn up anything so I hope someone enjoys as much as I did.
*This is a Microsoft hey-look-what-we-can-do type thing so software might try to be installed
